SEMP Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | 2134 B SL | In stanby, all normal power supplys, heating the resistor that powers the drive transistor, TV does not turn on | Altered or shorted zd202 zener diode zd202, it is tsound at the end of the general processor | To replace | Velk Dj |
| SEMP | TV-2934 (B) SL SK-9 | Power supply does not work, fuse blown, c607 shorted. (before maintenance/resoldering, the power supply was working or tsound was no short on the c607) | The technician must be careful with all circuits with strw6556a like the one on this TV, as the capacitor c607 (220uf/400v) is not automatically discharged by the str, even after several hours it may have some energy in it. | Discharge the capacitor before resoldering the str. If you forget to discharge and the fuse blows, if the c607 has a short circuit, remove the str and check if the short circuit has disappeared. | R |
| SEMP TOSHIBA | 32L2400 | Does not turn on, LED is on in stand-by | Icn805 1117-33 | Replaced the regulator n805 - 1117-33 (3.3v only gave 3.0v.) | Eletrônica Adiltec |
| SEMP TOSHIBA | LC3243W | Does not turn on, nor does the stand by LED | F820(f2a) and str-z2589 short | Solution in cases wsound replacing the capacitors has not resolved | Maike SR |
| SEMP | DL2971 | Does not turn on the backlight | Corrupted eeprom data | Rewrite the eeprom | wemersonwcp |
| SEMP | TV2050MAV U17 | I didn't tune into any channels. not even in automatic search | D101 altered 33v zener diode. | Replace it | Edfesom |
| SEMP | 2134 C SL | Dead | Str 6453a | Replace of the same | |
| SEMP TOSHIBA STI | DL2970(B)W DL3270(B)W DL3970(B)F LE3274(A)W LE3974(A)F DL2971(B)W DL3271(B)W DL3971(B)F | Sometimes when you turn on the TV, it doesn't tune to any channel. When you change the channel or turn it off and on, it works normally again. | Check 1v8 regulator u205 near the tuner. if it is below 1v8 (in my case it measured 1v3 defective) change the regulator. | Replace the 1v8 regulator u205. | rafaelmoraes99 |
| SEMP | TV2122 U19 | With vertical lines at the top of the screen | Leaky capacitors near the vertical ci | ,replace c-309 e 308 prox. do ci vertical | BICHYARA |
| SEMP | TV2134 CSL | High power supply above 200 volts and activating protection | R604 (2k2) open | After changing it, the power supply returned to normal, defect remedied. | Carlos eletronica , sao joao , PE |
| SEMP | TV2134 CSL | High power supply above 200 volts and activating protection | R604 (2k2) open | After changing it, the power supply returned to normal, defect remedied. | |
| SEMP | TV2134 (C)SL | Turns on and off by itself if you open the screen it appears vertically closed and turns off | D306 and sor switches and goes for the hug | God be praised | Rafael |
